最新报道:Anthropic requires all Claude users to decide by September 28 whether to allow their conversations to train AI models, extending data retention to five years for those who don’t opt out. Previously, consumer chat data was automatically deleted within 30 days. The change aims to improve model safety and skills like coding, reflecting competitive pressures for high-quality training data. Enterprise customers remain unaffected. Privacy experts raise concerns over user consent due to the opt-out design, which may lead to unintentional data sharing.
